Brookings County comprises the Brookings, SD Micropolitan Statistical Area.
The county was organized July 3, 1871, and was named for Wilmot Wood Brookings (1830-1905), a politician and pioneer of southeastern South Dakota. Medary was the first county seat, from 1871 to 1879, when it was moved to the city of Brookings.
Brookings County is on the east side of South Dakota. Its east boundary line abuts the west boundary line of the state of Minnesota. The Big Sioux River flows south-southeastward through the east central part of the county; its point of entry into Moody County marks Brookings County's lowest elevation: 1,568 ft (478 m) ASL.[4]
The county terrain consists of sloped flatlands, marked by numerous lakes and ponds especially in the western part.

Typical of the Great Plains, Brookings County voters are reliably Republican, even for a county with politics influenced by a college town. In only two national elections since 1932 has the county selected the Democratic Party candidate. Despite being reliably Republican territory, no Republican has taken over 60% of the vote since Ronald Reagan in 1984.
